create disk copy over the net without temp files

I wanted to create a copy of my whole laptop disk on an lvm disk of the same size.

Show git log beautifully

Single words from Amazon Kindle 3 notes

You can use any dictionary you want, in any language. This command will output all single-word annotations that you have underlined in your Kindle device (provided the file) given a list of language-specific words. If you want to learn vocabulary, this command is ideal.

What is my ip?

Find Out My Linux Distribution Name and Version

Shows what processes need to be restarted after system upgrade

emerge,apt-get,yum... all update your system. This will at some point replace either a runtime dependency or a process (which is still running). This oneliner will list what processes need to be restarted

Find number of computers in domain, OU, etc .

Get the full path of a bash script's Git repository head.

Rather than complicated and fragile paths relative to a script like "../../other", this command will retrieve the full path of the file's repository head. Safe with spaces in directory names. Works within a symlinked directory. Broken down: $cd "$(dirname "${BASH_SOURCE[0]}")" temporarily changes directories within this expansion. Double quoted "$(dirname" and ")" with unquoted ${BASH_SOURCE[0]} allows spaces in the path. $git rev-parse --show-toplevel gets the full path of the repository head of the current working directory, which was temporarily changed by the "cd".

Fast command-line directory browsing

After typing cd directory [enter] ls [enter] so many times, I figured I'd try to make it into a function. I was surprised how smoothly I was able to integrate it into my work on the command line. Just use cdls as you would cd. It will automatically list the directory contents after you cd into the directory. To make the command always available, add it to your .bashrc file. Not quite monumental, but still pretty convenient.

dump a single table of a database to file

(Debian/Ubuntu) Discover what package a file belongs to

Works similar to dpkg -S, but uses the locatedb and is thus inarguably a lot faster - if the locatedb is current.
